Interesting indeed. > I don't think we have any reports of problems on Linux yet. Don't some > versions of Linux use Qt as their native GUI engine?

I tried this now: * start LyX 2.0.2 from distribution disk image * open LyX users guide (english) and maximize it * start PDF view (in Preview) * scroll from top to bottom with two-finger swipe in Preview - at least 12..14 seconds * scroll from top to bottom with two-finger swipe in LyX window - 8..10 seconds I have to admit it looks more smooth with Preview. But I'd rate LyX feeling not that bad. Stephan PS. Numbers are taken by looking at the clock at the right corner of the menu bar. Perhaps not that exact...
